Redwood Play

Master Control Channel-in-a-Box

Redwood Play provides industry-leading master control branding and playout.

Depending on the model, Redwood Play has six or eight DVEs and two or four SDI inputs. All models have four HD video playback channels, four stereo audio players, four stereo mic/line inputs, an audio mixer, graphics with 32 layers of compositing, and a Character Generator able to receive external data feeds for crawls, tickers etc. It has a multiviewer, MAM, traffic interface, and workflow management.

It’s part of Aveco’s platform that includes high-end production and playout automation for discreet devices, as well as the industry’s first studio-in-a-box.

Redwood Play Architecture

Redwood Play is a client/server platform using a real-time operating system (QNX) in the Redwood server.

Redwood Play uses scripts which define the look of a channel. A traffic playlist is imported, and associated with the appropriate script. The transition types, DVE effects, graphics, overlays, audio mixes and all other aspects of presentation are executed with consistent precision.

A master control operator can take control manually when needed (e.g. breaking news, public emergencies etc.)

One Redwood server can host:
* Multiple Redwood Play units
* Multiple Redwood Studios (Aveco’s News-Studio-in-a-Box)
* Multiple studios and/or channels of Aveco’s ASTRA automation

Redwood Server

The Redwood server runs all system level applications including MAM and Master Control Automation. It provides workflow management and interfaces with traffic.

Redwood Server executes real time control of each software module independently, a “memory protection” feature of the QNX OS. Memory protection ensures a failure of any device or control module is isolated from having any impact on the rest of the system.

QNX is immune from worms and viruses that affect other platforms.

It’s a common operating system in satellites, aircraft, banks, tanks etc.

The server database is Sybase, well known for search speed performance and mission-critical resiliency.

Redwood Play Client

Redwood Play Client handles video I/O and all “Channel-in-a-Box” capabilities.

It has the production resources for sophisticated branding. The creative department of a TV station or network can accomplish outstanding transitions and promotions using Redwood Play’s considerable production power, listed above.

Operation is easy, for single or multiple channel applications and for local or remote site control.

It complements discreet-device automation as a simpler and less expensive way to air a channel by bringing MCR resources into one integrated box, as part of a larger system.

Redwood Play scales from 1 to 100 channels or more, one unit per channel, sharing a Redwood server.

Reduces Capex and Opex

Redwood Play lowers the costs of building and operating a new channel, or many channels, while maintaing a world-class look. The advantages of a channel-in-a-box are well known, but with Aveco the architecture extends to high-end production and master control automation supporting a vast array of existing equipment, in the same system, using the same user interface. This increases staff efficiency and simplifies engineering training and support.

Redwood Play Features

REDWOOD Play includes exceptional live production power compared to traditional master control.

Master Control Switcher: Two or four SDI inputs depending on the model, up to eight channels of DVE, audio/video mixing, and use of all resources below.

Internal Video Player: four HD channels each with stereo audio.

Audio Player: four stereo audio player channels

Live SDI Sources: two or four HD inputs, each with eight channels of embedded audio.

Graphics: A quality broadcast graphics system is provided, including animated text and graphics.

The graphics system uses external data feeds to drive crawls or tickers.

Graphic control scripts drive over-the-shoulder images, logos, titles, lower thirds, charts, graphs – with dynamic effects from up to 32 layers of keying.

Pre-built graphics can also be used (e.g. from Adobe, Autodesk etc.)

Audio Mixer: 16 channel digital audio, with four mic/line analog audio inputs.

Media Asset Management: An over-arching MAM is provided that includes active queries of playlists and file-transfer watchfolders. It provides unified naming conventions. It creates placeholders when traffic playlists include files not yet in local storage.





Based on a user-defined look-ahead, the MAM will automatically search online storage and pull files into the online storage. If scheduled files aren’t available at the assigned “alarm” time, the master control operator is notified.

For all users in MCR, media operations, traffic, engineering and others authorized to review media, the MAM provides video-audio-graphics search.

File-Based Workflow: File ingest is as simple as a file transfer drop folder which moves media to the on-air server.

Workflow Management: Many routine tasks can be handled automatically in Redwood Play through rules-based workflow scripts.

For example, a file transfer drop folder for incoming media might transcode files into the “house on-air format”, forward the file to a quality control subsystem, then upon its verified by QC, make a proxy. Other common use of scripts include automatic file processing notifcations to selected staff.

Storage: 2 TB local storage is standard with additional capacity as required.

Traffic Interface – With over 22 years of experience in Master Control, Aveco has interfaced to most traffic systems.

Users can also generate playlists manually, or use simple off-the-shelf tools like Microsoft Excel.

Multiviewer: The multiviewer displays program, preview, live sources, video player outputs and graphics sources.
